Men's O'Neill Psycho One 4/3 mm swimming wetsuit black 5421 (5421-A00)

Wetsuit O'NEILL Psycho One 4/3 mm  is a model that features 4/3 mm neoprene thickness, making it recommended for use on cooler summer days. The comfortable temperature range for this wetsuit is between 8°C - 11°C. 

The specially designed cut of the wetsuit ensures a minimal number of seams, which, besides increased freedom of movement, also provides protection against skin chafing.

The material used, TechnoButter 3 on the shoulders, arms, and calves, is a feather-light core made of ENVY foam rubber with uniquely enhanced stretch and hydrophobic neoprene. On the chest, back, buttocks, and shins, TechnoButter Firewall material is applied, which retains heat and ensures quick drying.

The outer layer of the neoprene features Aqua Alpha lamination, solvent-free, providing even better protection against water penetration.
